WebAbstract. The increase in small, battery-powered products has placed a spotlight on the power consumption of operational amplifiers (op amps). This application note discusses … WebFigure above shows the basic configuration in which the operational amplifier (op-amp) is used as a current to voltage converter. In this diagram a real current source is represented by an ideal current source i with infinite impedance coupled with a finite impedance R s in parallel. The equivalent voltage source is shown in the insert for ease …
WebAs the op-amps take no current at their input terminals (virtual earth), the same current must flow through the three resistor network of R2, R1 and R2 connected across the op-amp outputs. This means then that the voltage on the upper end of R1 will be equal to V1 and the voltage at the lower end of R1 to be equal to V2 .
